The SNP failed to answer very basic questions about what an independent Scotland would look like in terms of things like currency, EU membership, NATO membership, fiscal responsibility etc. They basically had no plan for what would happen next and the assumption would be that we would continue to use sterling, remain in the EU, have interest rates set by the Bank of England.
You are right there were a lot of questions left un answered, though I'm unsure how many of those were taken into account - half of the population only has a double digit IQ:cp:
Salmond was an oil economist (presumably of the mathematical variety, that's the sort that assumes perfect knowledge). Before 2008, the assumption appears to have been that Scotland would fund a generous welfare state on the proceeds of the oil and financial services sectors:hilarious::hilarious::hilarious:
I'm guessing that the Brexit referendum results now give a picture of where a majority of the Scottish population stands on EU membership.
The other questions are much more politically tricky. I can't see the German electorate being too keen on Scotland joining the Euro, when there are more than enough profligate PIIIGSS in the Euro zone already.
Germany always maintained a backup stock of Deutsch Mark notes so its entire stock of circulating notes could be replaced within 24 hours. AFAIK that option is still in place, and Germany could be out of the Euro in about 24 hours, if it ever needed to be.
Governments like to issue bonds as a way to raise money - it's politically easier for them to do that than it is for them to raise taxes, but to issue bonds on a large scale, they need access to a central bank and printing presses
Central banks either buy the government bonds directly, or accept them as collateral from banks in return for newly created fiat money - it's a way of concealing the fact that money is being printed for government to spend.
The Euro has the problem of being a "tragedy of the commons" where all euro zone government bonds were accepted on an equal footing by the European Central Bank, naturally the banks preferred the higher interest rate paid on dodgy Greek bonds to compared to sounder German ones
This resulted in a redistribution of wealth from Germany to Greece (at least until the ECB began to impose a discount on the now "junk" rated Greek bonds)
Prof Philipp Bagus explains the mechanism here

What the currency problem means, is:
No one else will want a Scottish state parasitically inflating their currency and transferring wealth to itself
That means that a newly independent Scotland would either have to issue its own new currency, and suffer the problems of its poor international acceptance damaging trade, and the unpopularity of rapid price inflation as the new currency is over printed
or, the independent Scottish state would be limited to circulating someone else's currency - and not be able to print any of it to spend itself.
Given that the Scottish nationalists and their supporters want large state sector spending and welfare state largesse, They're going to be well and truly screwed, they're going to have to choose from:
It looks like it will need to be England that secedes from the united Kingdom;)

I haven't mentioned Scotland's per capita share of the UK national debt Which is over 80% of GDP. The Stability and Growth pact for entry to the Euro Zone required keeping debt below 60% of GDP - though that was never enforced.

Regarding defense,
The Irish Republic is constitutionally neutral, and that works well
Going further, Iceland has no standing army and only a very limited defence agency
and further still, Costa Rica has absolutely no army or state sector defense agency
and Liechtenstein has only a police force and SWAT team
